Answer:
x=number of hours
c(x)= 25x+75
y-intercept= (0, 75)
Equation= y=25x+75
Slope= 25
Step-by-step explanation:
75 would be the y intercept(constant) because that's the initial charge for a call.
25 would be the coefficient for x because the hour you spend on the call varies.
The slope is how steep the line is, in this case it is 25.
x is the number of hours because that is the time that varies.
45
sorry if it is not what u needed
slope = 0
y intercept = -5
y= -5 is a horizontal line
horizontal lines have a slope of 0
it crosses the x axis at y=-5
-0.04x +17.2
3y^2 3√3y(end route) if you are simplifying, and (81y^7)^1/3 if you are rewriting it.
Step-by-step:
I know this!
